Application filed February 28,1918. Serial No. 219,683.

To all whom it may concern r Be it known that I, G s'roN'LnINExUenL LI] Coco, at Chateauneuf-sur-Loire, Department of the Loiret, France, citizen of the French Republic,- have invented certain new and useful Improvements in Hangars for Dirigibles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention has for its object a hangar for dirigibles consisting in the arrangement of four girder poles supporting two main suspension girders constituted by cables or chain bars supported by these four girder poles, the said main suspension girders carrying the ends of the main stays of secondary and transverse girders which with the coverin constitute the roof which is independent 0 the walls and thevertical and lateral partitions of the hangar erected in the form of traveling doors which can be moved on rails and constitute a form of outer harbor which is necessary for the entrance and exit of the dirigible.

The invention is hereinafter described in detail with reference to the accompanying drawings which illustrate by way of example and diagrammatically one form of the hangar embodying the invention.

Figure 1 is a view in longitudinal elevation of the improved hangar.

Fig. 2 is a plan view of the hangar illustrated in Fig. 1.

Fig. 3 is a transverse sectional view of the hangar.

Figs. sand 5 illustrate the different arrangements of the movable doors to constitute the outer harbors. r

The hangar is constituted by four vertical girder poles a a, b b, carrying two main suspension girders A A of cables or chain bars. Each of these main girders is located in the same vertical plane as the girder poles at a, b b, of the two longitudinal sides of the hangar and have depending therefrom roof supporting main stays A. The ends of the mainstays and the secondary and transverse girders t, which with the braces and cover constitute the roofing of the hangar, bear upon these two main suspension girders. The weight of this roofing rests therefore entirely on these four poles at a,

b 6 This roofing is made to be stable and rigid by itself being'in the form of assuspended platform. The suspended roofing being thus independent of the walls and the lateral and vertical partitions, it issufli'cient in order entirely to close the hangar, to constructmovable partitions or. doors. This is effectedby providingvertical partitions or doors 2) p, with transverse partitions connected at e mounted on rollers g and being adapted to travel on rails o o, arranged in such a manner as to create by suitably disposing these partitions or doors, an outer harbor which is necessary for the exit and entrance of the dirigible. The plan view of these rails, in Figs. 4 and 5 in particular, represents by way of example the general disposition in one direction or the other of the articulated doors constituting the longitudinal walls of the hangar. The rails 22 and '0 supporting the movable partitions or doors are arranged longitudinally of the hangar on both sides thereof and extending beyond the ends of said hangar bendingoutwardlytherefrom in a gradual curve, as clearly shown in the plan view of Fig. 2. It will be obvious from this construction that when the side partitions or doors are moved longitudinally of the hangar in either direction, they will follow the course of the track and form the necessary wind breaks. or harbors desired.

Dependent upon the direction of the wind,

upon the exit or entrance of the dirigible,

one or other of the series of doors is manipulated; thus for a wind blowing at right angles to the wall between the girder poles b b of the hangar (that is to say in the direction of the arrow shown in Fig. 5), the

doors between the girder poles a a may be opened either partly at each side to the p0 sitions a a,, or entirely on one or both sides to the positions a a and a, a,. The same conditions would apply if the wind were blowing at right angles to the wall between the girder poles a a instead of between b b, that is to say in the opposite direction.

If, however, the wind is blowing in a direction at right angles to the transverse wall between the girder poles a I) (see Fig.

4) the doors between the girder poles a1, a-

will be moved along the entire length of rails to the positions (L a a" and the doors between the girder poles b I). to the positions 6 b I)".

By this means a large outer harbor is provided permittingthe easy maneuvering of the dirigible both in entering and leaving the hangar. 7

From the aibovedescription it isapparen't that by forming the hangar in this manner the exit or. entrance of a dirigib'le on one side of the hangar or the other in accord-' ance With the direction of the Wind is facilitated. Movable doors may be placedon every side if desired but in practice, it Will befound suificient to provide movable doors on the two longitudinal sides of the hangar only;

I' claim: w

'A hangar for dirigibles comprising four separate girder .poles, main girders extending between and suspended at each end from the girder poles, a roof or cover supporting 'vvalls whicharesupported on said rails independently of the poles, suspension girders and cover,-'and are movable to positions to form harbors at the ends of the hangar, but adapted to cooperate with the roof or cover when in a normal position to form a complete housing or hangar. V i testimony whereof I afiix my signature. in presence of a Witness.
